I can't remember if this was done before, but --- Post your oldest bimetallic coin: Italian Republic -- 500 lire, 1982:   1) Coin must have two or more areas with different metallic composition, when viewed face-on (excludes plated or clad coinage, painted coins, coins with a silver wash, etc., and coins with glued-on bits of glass or plastic, meteorites, etc., applied after the coin was struck) 2) The number of points is numerically equal to the last date the coin could have been produced, converted to the usual AD/BC calendar. Any coin with 2021 or later date will get 2021 points. The challenge coin gets 1982 points. 3) The entry with the lowest number of points will win this round 4) If a user submits more than one entry for this round, the one with the lowest point score will be used. 5) Entries with an ineligible coin, or no coin will receive 2022 points -- these may win the round, if nobody submits a valid entry. If nobody posts anything before the time limit is up, the CCF staff will determine the winner. 6) In case of points tie, earliest entry will win 7) There is no bonus or penalty for posting an exact match of the challenge coin 8) Coins need to be as minted by a valid government (no fantasy coins, no replicas, no non-coin items (coasters, ashtrays, for example), no private advertising tokens, no transit tokens, etc.) Commemorative and NCLT coins are allowed 9) The cutoff for new entries is 2020/06/16 at 19:30:00 forum time (EDT) |

Do you mean bimetallic as in these things with rings of different metals or coins made of 2 or more different metals.
If its the latter, you can have a Lydian stater from 680BC as these were made out of electrum, a mix of gold

Rings of different metals. If it was alloys then just about any coin would have counted.
I think silver-plugged coins would technically qualify, though, so it's still possible to get ancient.

Well actually the challenge coin would have 2001 points as it was 2001 the last year it was produced. All I could find was a one off issued by New Zealand in 1994 A Bimetallic 50 cent coin, this version is cupro nickel ring with aluminium bronze centre. A silver/nickel version was also issued.   It was issued in sets (My budget one - UNC) and silver for the Proof set but never circulated - was legal tender (Nothing in your rules mentioned that). |

Although coins made of alloy may show microscopic grains of differing metals and intermetallic compounds, eligible coins for this round will have rings (or other shapes) made of different metals. |

Seeing how I can't seam to find my silver plug cent, I guess I will go with this. 1987 Italy 500 Lire   That's assuming It was minted in 1987 |

I think that Axumite units are likely the ultimate winners of this challenge, but I'm not convinced that the couple I have didn't have the gold stripped away at some point over the last 1500 years and then added back when dug up to prepare the coins for sale. However, I picked up this tin Farthing (dated 1685) earlier this year from Frank Robinson:   "If you climb a good tree, you get a push."

The absolute first bimetallic "coin" (if they can be considered as such) were medallions minted by a handful of 2nd-century Roman emperors - they were special gifts presented to prestigious friends and political allies of emperors, and probably had some nominal face value, likely two-sestertii. Bimetallic medallions were mostly an orichalchum (brass) disc set in a bronze ring. Spence might be right about Axumite coinage being the first bimetallic circulating coins, although they had small amounts of gold leaf applied to the surface, rather than having a true core of one metal set inside another. Oldest one I have is this, from central Asia: Turco-Hepthalites Vajara Vasudeva, ca 680-720 AD Silver drachm with gold plug  Probably 98% of all of these coins have a gold plug, always in the neck of the portrait, and probably applied either during or shortly after minting to bring the exchange value up to par with another coinage, likely with the slightly heavier drachms used elsewhere within the Turkic Khaganate realm, with the early Gadhaiya Paisa, or with the more pure Umayyad dirhem. Early examples have a shiny gold plug, whereas later ones (like mine) have a copper-gold alloy plug. |
